Question

Please help me with this problem

Answer 1

Answer:

y = - 2x

Step-by-step explanation:

Given that x and y vary directly then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition x = - 5, y = 10, thus

k = $\frac{y}{x}$ = $\frac{10}{-5}$ = - 2, hence

y = - 2x ← is the equation relating them

Answer 2

Answer: the answer is 23x . i double checked by the way.
